Base Elise AutoX Tires
Hardware: bone stock 2009 Elise. I just picked this car up a couple of months ago and the last owner had recently replaced the tires. It's currently equipped with OEM replacement Yokohama ADVAN Neova AD07's. That's my problem...I want to run this car in SCCA Solo street class (SS) and unfortunately the AD07's have a UTQG of 180. Minimum UTQG for street classes is now 200, so what to do? I would like to keep the OEM Elise wheels as going wider, even to a standard LSS width up front, will require that I apply ALL of the LSS options to the car in order to run it in SS class. So...I'm really at odds with tire size options for the narrow 5.5-inch front wheels. I've spent a few hours reading the tire related forums here already and either found this issue not addressed with regard to SCCA, or met with skepticism and doubt (like whether or not it's a good idea to put 205/50/16's up front and then run hard on track day).
I'm pretty well convinced that a 5.5-inch wheel should not have more than a 195 width mounted. There are not a lot of good track tire options in this size (be that 195/45/16 or 195/50/16). On the rear, there are many ways to go, however, I don't want to upset the balance of the car and am concerned as to what impact a 245 width on the rear may have (should I go that wide). To add to these dilemmas, it appears that some of the favorite tires are no longer available in the sizes what work for me.
Anyone running SCCA Solo SS right now with a base Elise? What is your tire configuration and how do the handling characteristics compare to your stock setup?
